DIRECTION and Time |
|
Galileo breakthrough in motion |
Defining a new state of motion: th inertial state of constant speed and direction |
|
What galileo learned about acceleration |
1. Must fit nature 2.free fall is the prototype of of all acceleration 3. Continually acquiring new increments of speed 4.repeating itself in the same manner |
|
Newtons 1st law |
Objects preserves it's state of constant rest or of velocity unless it is compelled to change that state by forces acting upon it ( bus example) |
|
Newtons 2nd Law |
Objects acceleration from a net force is propertional to net force inversely proportional to its mass and same direction of net force |
|
Newtons 3rd law |
With every action there's and equal but opposite reaction (skateboard) |
